  • Information processor
    Patent number: 9449179
    Abstract: Disclosed herein is an information processor that allows for manipulation of raw data to a certain extent with an application program while protecting the content of raw data. The information processor acquires encrypted media data, decodes the encrypted media data to generate raw data, scrambles the raw data to generate scrambled data, descrambles the scrambled data to generate the raw data, and outputs the raw data to a player.
